This was located between the air filter and the turbo inlet. It supposed to quiet down the turbo whine a little and make for better airflow into the turbo from what I have read. Anyone know what the real reason is for it and if the warranty can be voided if it's removed? I am not comfortable with it being in the intake tube due to the fact that if the foam deteriorated it would go right into the turbo, intercooler or worse the engine.
